1. i have a panel on a windows form with picture boxes in.I wish to click on one and open a specific directory on my pc , much like clicking on one in explorer.
2. is it possible to run executables with options? i.e wmplayer.exe" /prefetch:1 if i use shell it throws an error obviously.
3. is it possible to open windowsa control panel items from within my program,like network and sharing. I am using win7 and VB2008
I am in need of a form that shows various options, exactly like the Options in Visual Studio. Since there are so many options I too want them categorized, with a TreeView to the left taking care of showing the right category.The usual 'easy' approach here would be to just place a TreeView control on the form, add some nodes, and give those nodes a tag or key that corresponds to a panel or UserControl with the options for that category.Since there will be a lot of options however, this is not really feasible design-wise; the form would be cluttered with possibly 50 panels, all of which I would need to select and bring to front from time to time to add controls to them that represent the options.
So I decided to create a custom control that does exactly that. The control is very similar to my Wizard usercontrol, users can add OptionsPanels at design time, which inherit Panel and simply represent one panel of options. When they do, the panel is added to a container panel, and at the same time a TreeNode is added to a TreeView. The control uses a custom ControlDesigner to handle design-time clicks in the Treeview, selecting a different node would select and bring to front the corresponding panel, allowing the user to add the controls he wants.
Due to the design time support the problem of having 50 panels is no longer present, only one panel will be visible at a time and selecting the right panel is as simple as selecting the corresponding TreeNode, just as during run-time. Anyway, I got all this working, but only for a single 'level' of categories. As you can see in the Visual Studio options, there can be multiple levels of categories. For example, the Environment node has a bunch of children, where each child represents one 'options panel'. There can even be deeper nesting, see the Text Editor node for example.Let me begin by drawing out the basics of how my control works so far.
The main control is an OptionsView control, which contains a SplitContainer with a TreeView to the left and a OptionsPanelContainer to the right. The OptionsPanelContainer is merely a Panel to which only OptionsPanel controls can be added, and which raises events when this happens, as well as when OptionsPanels are removed from it. An OptionsPanel also inherits Panel, and these are the actual panels the users will see in the control, one for each option category.For now, each OptionsPanel has exactly one corresponding TreeNode (and vice versa). In the Visual Studio options, each 'parent' category usually has a 'General' node as the first child, and the parent and this General node show the same option panel, but I am ignoring that for the moment.
The OptionsView control has a property Panels that returns the ControlCollection (Controls property) of the OptionsPanelContainer (in other words: it returns a collection of OptionsPanels that are in this container panel).
vb.net
<Editor(GetType(Designers.OptionsPanelCollectionEditor), GetType(UITypeEditor))> _ <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Panels As Control.ControlCollection Get Return Me.PanelContainer.Controls End Get End Property
A custom CollectionEditor for this property takes care of the designer: even though the property type is ControlCollection, the CollectionEditor knows it should create instances of the OptionsPanel control instead of just Controls.When it does this, a corresponding TreeNode is also created and its Tag property is set to the OptionsPanel. Vice versa, the Node property of the OptionsPanel is set to the node. Hence the node and panel both know their corresponding object.
vb.net
Public Class OptionsPanelCollectionEditor Inherits System.ComponentModel.Design.CollectionEditor Public Sub New(type As Type) MyBase.New(type) End Sub Protected Overrides Function CreateCollectionItemType() As System.Type
[code]....
So far so good, this all works fine. I can add Panels via the designer and when I do a new TreeNode appears in the TreeView. I can select this node and the panel becomes visible (comes to the front).Now, I am a little stuck. How do I implement child option panels? And more importantly: how do I let the user add child panels?The most logical choice I think is to let each OptionsPanel have a property (ChildPanels or something) that returns the child OptionsPanels for that panel. Once the user selects an OptionsPanel then, he can look in the property grid to find its ChildPanels property and add child panels to that.
There is a problem though: what would this property return? It must return a ControlCollection of some container (this is, I think, a requirement for the designer features to work, otherwise panels are not added to the Form.Designer.vb file). But there is no container. I cannot add them to the OptionsPanel itself, that would make no sense because the parent OptionsPanel has its own set of controls (the options itself...), there cannot be another (fully docked) Panel on top of those obviously.The container of the main OptionsView then? That is not an option either, its Controls collection holds ALL OptionsPanels, not just the children of the selected panel. I cannot 'select' only the right panels either, that would require me to return a new instance of ControlCollection, it would be impossible to return the actual ControlsCollection that holds merely a small selection of its controls.
I am working on a project where I am required to create four executables from the solutions I have been working on and I am unable to get them to work on an alternative computer.
When I use the publish tool and publish them on my desktop they work without any problem but if I put these on a sub folder or on another computer then they do not work, I have been told that I need to create an installer file .AS or something but I am unsure how to go about it
I would be very grateful if someone could tell me how I can create an executable that will run on any computer other than the one it has been developed on.
what i want to do, is have a user select a file. And then the program displays the icon associated with that particular file. Would this be hard to do? And if its easy, can somebody give me an idea on where to start?

View 5 RepliesI am converting an older software package written in VB 6 to VS 2010.Not to incredibly painful but planning for the future as we have had lets say a few issues with VB 6 on our current layout of multiple OS and this is my first real project lead.We are a smaller job shop and we move on a rotation of new PC's/OS's come in to replace broken or exhausted older PC's in the front office and move the older PC's out to the shop floor.We have an array of different OS's ranging from Windows 98 and Windows 7 (32 bit and 64 bit OS). By the time I am done with the conversion we should be sitting comfortable with a range of PC's from XP and up. When creating the executable for my project is this something that can be handled ahead of time, creating multiple executables for specified OS, or an all in one package executable?I was looking to see what people had as suggestions at handling this.We haven't even bought VS yet and are looking at the VS 2010 Premium package, do I need Ultimate?

View 5 Repliesi have various options in my app, some complex some not, these 2 save on application exit and reload on application start themes, and layouts. There selected via a comobox each.So onto the question, how does everyone create options menus? With out using a menustrip/toolstrip?
The method i was using , was to have a picture box show a panel when it was clicked on, the panel had all the various options etc on it. This idea worked great, but meant working in design mode was a pain because the panel and everything on it had to be moved round to see the items under it on the form.
So today i decided to see what other ways i can implement a menu, and i changed it so the picturebox/button now opens a dialog, and all the options etc are on that dialog, this works great except options such as the combobox 1 and combobox2 last used setting (text data binding) doesn't load when the application is started, they only load when you go into the options. Which defeats the point, if a users going into the options just to load the settings its useless them been saved.
The time to initialize the dialog (for it to appear and be click able) is 5 - 15 seconds, not alot i know but the 1st method of using a panel it initializes instantly, but then its never really closed just made hidden, so i uses more system resources.So how does every one else implement there options menu?
im new to programing infact this is my second day... im unsure of where to ask this question and i know this is probably not the hardest thing to do lol, i am making a "launcher" to launch a few games, a webbrowser and a few other things, however to do this i have a "set path" in the code, i want to know if anyone can help me make a "setup page" so the user of the launcher can set the path [eg]- to launch firefox i have If IO.File.Exists("C:Program FilesMozilla Firefoxfirefox.exe") Then Process.Start("C:Program FilesMozilla Firefoxfirefox.exe")not everyone has firefox installed to that exact location , so i need to make a settings page to set the paths, each file is launched buy a single button, in the future i may even make another program much the same for people who dont know how to use a pc nd just want to check emails and browse to a webpage.
View 12 RepliesAs i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.
We have become disenfranchised with our med records scanning package and are doing in house development to create our own. With most of the interface built out, the monster of calling the Fujitsu Twain driver and pre-setting scan options is what I am looking for. Fujitsu does not have an SDK available on their web for this.

I want to learn how to add the menu options that appear when you click your right mouse button.So far I have a normal menu strip control, rich text box control and I have added a ContextMenuStrip control.
I have not got a clue on how to set the properties for the contextmenustrip on the richtextbox control, so when the user clicks the right mouse button the contextmenustrip appears.
Ok lets say I have a combo box with like 3 options in.
Ex:

Option 1
Option 2
Option 3

I've got a project where each "person's profile" will have many options associated with them, they are broken into groups such as
"Hobbies"
"TV Shows"
"Dinners"
What I was going to do it tick each "group" that applies to each profile and show only the fields that apply to the user.I was going to display them on a panel or a tabpage but How would I show the user what panels need data entered? (there could be 3 or even 4) but would the panels 2-3(or 4) be hidden how would I promt the user to enter data.I don't like the "look and feel" of tabpages.
Well my project will basically involve a database of the sports info of students in my school. It has to work with about 1000 profiles, each containing a personal info record (basically an address book) and a Sports Info record which has some simple information like what sport they do for winter and summer but it also has some records like "Training Info" which will contain a some 10 fields. It'll wind up something like an array of records of records of records.
One of the key points for assessment is that we employ search and sort functionality explicitly using algorithms that have been provided to us. Essentially we'll have to write up our own subs for binary searches and stuff like that.
Now this is group work and I was put in charge of making the database, one thing I'm unsure of is what I should use. Most of the other groups are using .txt files to store their databases as they've been told that these are easier than Access files. However their databases don't appear to be quite as complex as the one my group's planning. Another random titbit of info I heard was that using our own search functions to search an Access file would not only be slower than using the inbuilt ones (another random something gleaned from conversation) [does it have inbuilt search functions?? I heard somewhere else it didn't] but also that it'd be slower than searching a .txt file with a similar sub.
I'm not sure of the veracity of those statements, however I still want to ask if you guys have any recommendations for what I should use to make the database with. The only ones I know of are CSV text files and MS Access, I'd be very grateful if you could point me in the of a good "thing" to use with VB.net for this kind of project.
